$BTC Bitcoin (BTC) is the world's largest decentralized digital currency, operating on a peer-to-peer network without banks or government control. Created in 2009 by the pseudonymous Satoshi Nakamoto, it uses a public ledger called a blockchain to ensure transparent, irreversible transactions.Here is the essential information you need to know about Bitcoin:Strict Supply Scarcity: There will only ever be \(21\text{ million}\) bitcoins created. This mathematical limit is programmed to prevent inflation and functions similarly to a digital version of gold.How Transactions Work: When you send Bitcoin, the transaction is verified by a global network of computers (miners) and permanently recorded on the blockchain. Once completed, transactions cannot be altered or reversed.Extreme Volatility: Bitcoin’s price is largely driven by supply and demand, and it is known to experience massive price swings. It should be treated as a high-risk asset rather than a stable place to store your primary savings.Self-Custody & Security: Your Bitcoin is stored in a digital "wallet" secured by private cryptographic keys. Owning these keys gives you complete control over your assets, meaning you must safeguard them against theft or loss.If you are looking to get started, you can buy, sell, or trade Bitcoin through recognized financial apps and cryptocurrency exchanges like Coinbase or Binance.
